At this time, you can only create up to 5 automatic discounts using Regios Automatic Discounts.
This is due to restrictions placed by Shopify. We don't know if or when they will remove or relax this limit.
However, we plan to communicate with Shopify to get clearer communication on the reasons behind the limit, and whether there are any plans to adjust it.
I encourage you to comment on or subscribe to this thread, so you can stay updated on the progress.
